I have 5 kids and 2 nephews and some of the highlights have been:
Whole full giant container of foot powder...all over my bedroom!
Powdered Nestles Qwik...all over kitchen, and they tried to 'eat it' so there was wet fingerprints and even some tongue prints on the island. Nice.
Full container of liquid laundry soap + Costco sized container of Resolve stain remover + pee...luckily they dumped it all in a bucket in the laundry room but that was A. EXPENSIVE mess...and don't even get me started on the pee part?? I was so angry...but apparently pee + laundry soap makes great bubbles? ICK!
Dry erase markers the whole length of the wall going downstairs into the family room.
And this one was not there fault but it was THE WORST, IMO! We were on a road trip, went thru the drive-thru for lunch & got the 2 boys (all we had at the time) milkshakes....youngest son got a stomach ache and proceeded to puke ALL over...and in doing so, made his older brother gag and puke ALL over his side of the car! Chocolate & Butterscotch milkshake puke mixed in w/chicken nuggets & fries is DIS-CUST-ING!!! And of course we were in the middle of nowhere at the time, on the freeway and all we had was a travel size wet-wipe container and the left over napkins from lunch to clean up the mess. Thankfully hubby has a strong stomach...my portion of 'clean up' consisted of changing the kids' clothes!
